A real favourite of mine. Some of the more epic Bathory influenced Moonblood stuff like Siegfried, Fullmoon Witchery, etc. is quite akin to Nachtfalke.

Doomed to Die is my favourite, with its amazing production and songs, but Hail Victory Teutonia is probably the best start point. Even As the Wolves Died and Wotan's Return, the comparatively weaker of his albums, have some killer tracks. Following the Wanderer's Path is a little different due to the clean vocals, but great if you can get into them.

His albums are a little inconsistent in general, but the best tracks are amazing.
